PLS-GENETIC ALGORITHM TOOLBOX by Riccardo Leardi

Dear All, the tool box "PLS-Genetic Algorithm" available available here http://www.models.life.ku.dk/GAPLS. The problem is that i want to run to run this tool box but dont know how to do that? I have my own hyperspectral data on which i want to run this tool box. the code mentions "dataset", what changes do i make so that I can run it on my own data to check results. Any help would be highly appreciated. Thanks

According to the manual,

The data set must be a o,x+1 matrix, in which each line is an object, the columns 1:x are the X variables and the last column is the Y variable.

Walter Roberson thanks for the answer, There are two methods of GA and PLS in HSI data, this tool box uses binary data and i want to perform it for Direct method. To be specific GA chromosomes in this package are in the form of 1,0 and i need chromosomes to be made of true value of Spectral Signatures corresponding to each wavelength.

You could be right, but that is not how I interpret the manual. I would need to experiment with a dataset -- do you have a test dataset of reasonable size you could attach?

Hi Walter, I am exploring the code, but I keep having this issue.

Although, I am usng a non-HSI data but just starting with the GAPLSOPT is throwith this error:

"Error in gaplsopt (line 24)

randomiz"

What can I do? I guess I am doingn something wrong.
